I am looking into taking this list into a casual tournament. Wondering what you think about it's control value.

What about this:

This means no stress..

What I like about mix of Tactician and Ion Cannon is that the defender gets to move one straight and will have no actions at all. I can try to get out of his range with barrel roll or get behind him with K-turn and keep ioning or simply attack with red 4 dice.

The plan is to get into R2 and fire Flechette torpedoes (if defender has Hull<5). In R2 that would give immediate 2 stress even without scoring a hit! In most cases this makes him much more predictable, hence I assume I can get him in my arc, while he has no dice mod (due to second stress) and get him ioned.

Against swarms I would give no effort to double stress, depending on situation either hit or ion. Against big ships or "shields heavy", I still can do a double ion with 2 stress following with plasma torp to get rid of shields better.

I am just not sure if 1 agi Bees would live long enough to start controlling their enemies...

I like the idea, but I don't think flechette torps are necessary. Once you ion something, its very easy to get into R2 for a followup stress + ion next turn, and that ship is basically toast after that (except really high hull stuff, but with 3 ions, it should be trivial to control them).

Your biggest concern will be arc-dodgers, because with only 3 b-wings, you will struggle to get them in arc of more than one ship, and one ion shot might not be enough...

The potential new 'alpha strike' meta that may become popular in the near future will also be problematic (but that's still a bit down the road and not certain to pan out yet...)

Personally, I think a modified 'panic attack' list is ultimately better because 4 ships are greater than 3.

For example:

2 blues w/ E2 + tactician

2 blues w/ ion cannon

100

Flechette torps is too much IMHO. Dropping them and the other torps and something nets you enough for a blocking z-95.
